As usual, there is more than one way to achieve the goal here. You can use the standard AE t bar set up and modify the chassis to lower the roll center (Laje, Hyperform) or leave the chassis alone and change where the center of the pivot is on the t bar (OD, Slapmaster)

Sorry, I'm not answering your question A one-off chassis would be quite expensive, like at least double. PM me if you would like more info
